摘要:
A fixed-line trimmer head for a rotary trimmer device includes the upper portion having a periphery, wherein the upper portion has a plurality of openings spaced from the periphery; and a plurality of mechanisms. Each mechanism can hold a strip of line and includes a post portion disposed through one of the openings in the upper portion, and a flange disposed at one end of the post portion and sandwiched between the upper portion and lower portion of the trimmer head to prevent vertical movement of the mechanism. The post portion includes two line channels, each line channel defining a passageway to receive the same strip of line, wherein at least one of the line channels is curved such that any portion of the strip of line being received through the passageway of that line channel is bent at that portion of the strip of line away from the second line channel while passing through that at least one line channel that is curved.
